Express f(x)=3+|2x-5| as a piecewise function WITHOUT using absolute value
Please give a detailed response not just answer to help me understand
Answer:
[tex]f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 2x-2& \quad x \geq 5/2 \\ -2x+8 & \quad x < 5/2 \end{array} \right.[/tex]
Step-by-step explanation:
We are given the function:
[tex]f(x)=3+|2x-5|[/tex]
Remember that by the definition of absolute value:
[tex]\displaystyle |x|= \left\{ \begin{array}{ll} x & \quad x \geq 0 \\ - x & \quad x < 0 \end{array} \right.[/tex]
Our absolute value is:
[tex]|2x-5|[/tex]
First, we will find when it becomes 0. Set the equation equal to 0:
[tex]2x-5=0[/tex]
Solve for x:
[tex]x=5/2[/tex]
So, we can see that for all values greater than x = 5/2, 2x - 5 is positive.
For all values less than x = 5/2, 2x - 5 is negative.
Therefore (the positive case go above, and the negative case go below):
[tex]|2x-5|= \left\{ \begin{array}{ll} 2x-5 & \quad x \geq 5/2 \\ -(2x-5) & \quad x < 5/2 \end{array} \right.[/tex]
Finally, we can add a three:
[tex]f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 3+(2x-5) & \quad x \geq 5/2 \\ 3+(-(2x-5)) & \quad x < 5/2 \end{array} \right.[/tex]
Simplify if desired:
[tex]f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 2x-2& \quad x \geq 5/2 \\ -2x+8 & \quad x < 5/2 \end{array} \right.[/tex]

the length of the rectangle is 7 cm less than 4 times its width the area is 15 square cm
Answer:
I guess the answer is 4.4 cm or 22/5 cm
Step-by-step explanation:
AREA= 15cm^2
Let the Breadth be x
Length= 4x-7
Area = l×b
15 = 4x-7×x
15+7=4x+x
22=5x
22÷5=x
4.4=x
Therefore, Breadth= 4.4cm Length= 10.6cm

What is the inequalities that are possible.
Answer:
We conclude that:
[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
The solution graph on the number line is also attached.
Step-by-step explanation:
Given the inequality
[tex]-8x\:\le 32[/tex]
Solving the inequality
[tex]-8x\:\le 32[/tex]
Multiply both sides by -1 (reverse the inequality)
[tex]\left(-8x\right)\left(-1\right)\ge \:32\left(-1\right)[/tex]
Simplify
[tex]8x\ge \:-32[/tex]
Divide both sides by 8
[tex]\frac{8x}{8}\ge \frac{-32}{8}[/tex]
Simplify
[tex]x\ge \:-4[/tex]
Therefore, we conclude that:
[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
The solution graph on the number line is also attached.

What is y when x =17
Answer:
The answer is 30
Answer:
y = 30
Step-by-step explanation:
There are 2 ways to find the answer to this.
#1
The relationship between x and y is y = x+13.
x is 17 so 17+13 would equal y.
17+13 = 30
y = 30
#2
rule for y: y increases by 4
26+4 = ?
26+4 = 30
y = 30

Solve y = x + 6 for X.
x= y + 6
x= -y + 6
x = y - 6
x= -y - 6
Answer:
x=y-6
Step-by-step explanation:
First, flip the equation.
x+6=y
Finally, add -6 to both sides.
x+6+−6=y+−6
x=y−6
In a company, 65% of the workers are women. If 1820 people work for the company who are men, how many workers are there in all?
Answer:

6. Write an equation for a line that passes through (6, 12) and (10, 20).
Answer:
Step-by-step explanation:
Y = mx +b / Slope intercept form
mx - y = -b / Standard form
6m -2 = -b / Plug in ( 6,2)
-9m -10 = -b / Plug in ( -9, 10)
Solve the system of equation for m and b.
6m -2 = -9m -10 , then 15m = -8 m = -8/15
b = -6m +2 ,then b= -6 ( -8/ 15) +2 = 78/15
-8/15 X - y = - 78/15
8X +15y = 78 / Equation of in standard form
Note: This is a different methods of solving this problem. All methods find their roots coming from the basic premises.
Equation of a line in the slope intersect form is
Y = mx +b
To convert to standard form of ax + by =c
Simply move over the parameters
mx - y = -b where a = m , and c = -b
Then we feed coordinates of 2 points in there
make a 2 equation with 2 unknown( m,b) to
solve.

Brian has 8 feet of canvas. He needs 1/4 foot to make a painting.
How many paintings can Brian make?
Answer:
32 paintings
Step-by-step explanation:
You have to divide 8 by [tex]\frac{1}{4}[/tex]
turn 8 into a fraction by putting a 1 under it, [tex]\frac{8}{1}[/tex], and flip the other fraction, [tex]\frac{4}{1}[/tex]
now, you multiply the fractions
[tex]\frac{8}{1}[/tex] ×[tex]\frac{4}{1}[/tex]= [tex]\frac{32}{1}[/tex], so you get 32 over one, which you can just simplify into 32
Brian can make 32 paintings.
The solution is, Brian can make 32 paintings
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
You have to divide 8 by
turn 8 into a fraction by putting a 1 under it, 8/1 , 4/1 and flip the other fraction,
now, you multiply the fractions
8/1×4/1=32 ,
so you get 32 over one, which you can just simplify into 32
Brian can make 32 paintings.
